Technical Field
[0001] This utility model relates to the field of cryopreservation and thawing technology, specifically to a cryopreservation bag kit and cryopreservation rack. Background Technology
[0002] Cell cryopreservation is one of the main methods of cell preservation. By placing cells at low temperatures, cryopreservation technology allows cells to be temporarily removed from their growth state while preserving their cellular characteristics, thus serving as a means of cell preservation. Cryopreservation bags are flexible plastic bags used to store biological samples in this cryopreservation environment. For example, Chinese Patent 201921386593.4 discloses a cryopreservation rack for cryopreservation bags, comprising: a frame body with multiple compartments arranged sequentially along its length, each compartment being open at both ends and interconnected with adjacent compartments; and at least one cryopreservation bag holding box, in which each cryopreservation bag is respectively placed.
[0003] Regarding the aforementioned existing technologies, in the current use of cryopreservation bags and accessories, during the thawing of cryopreservation bags, it is necessary to remove the cryopreservation bags from the cryopreservation racks and cryopreservation protection boxes. In order to avoid damage and contamination, after removing them, it is also necessary to put the cryopreservation bags into sealed bags and then place them in a water bath for thawing. If it is necessary to avoid holding the cryopreservation bags and immersing them in water for thawing, additional clamping tools are required after putting them into sealed bags. This results in many operation steps, which can easily lead to misoperation and prolonged time consumption, resulting in poor thawing quality. Utility Model Content

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0039] To address the technical problems of numerous resuscitation steps required for cryopreservation bags and accessories, which can easily lead to misoperation and prolonged processing time, this utility model provides a cryopreservation bag kit. This kit provides basic protection by inserting a protective frame into the cryopreservation bag. In use, the lifting frame, combined with the protective frame, allows the sealing bag to be simultaneously placed into the water while the cryopreservation bag is being retrieved. The lifting frame allows the protective frame and the sealed bag containing the cryopreservation bag to be immersed in water. Furthermore, the protective frame restricts the position of the cryopreservation bag in the water bath, ensuring full immersion without the need for additional clamping tools.
[0040] It should be noted that the cryopreservation bag kit of this utility model is used for, but not limited to, cryopreservation bags. For ease of explanation, this utility model only uses the application of the cryopreservation bag kit to cryopreservation bags as an example. The principle of the cryopreservation bag kit applied to other types of equipment is essentially the same as that applied to cryopreservation bags, and will not be described in detail here.
[0041] Please see Figure 1-8This utility model provides a cryopreservation bag kit assembly, which includes a protective frame 1, a lifting frame 2, a clamping component 3, and a sealing bag 4. The protective frame 1 has an opening 101 on one side for inserting a cryopreservation bag 7. The protective frame 1 protects the cryopreservation bag 7 during freezing, preventing impact. A guide groove 102 is formed on the protective frame 1 along the insertion direction of the cryopreservation bag 7. The guide groove 102 is a strip-shaped groove and communicates with the opening 101, penetrating the inner top wall of the protective frame 1 from top to bottom. The lifting frame 2 is slidably connected to the guide groove 102, used to hook and lift the protective frame 1. The lifting frame 2 is inserted into the opening of the guide groove 102 at the opening 101 and slides along the guide groove 102. Move to the end of the guide groove 102, hook the protective frame 1, and the protective frame 1 can be lifted and moved; the clamping part 3 is installed on the lifting frame 2 and has a clamping end for clamping the sealed bag 4 and connecting it to the lifting frame 2; the sealed bag 4 has a bag opening 401, and one side of the bag opening 401 of the sealed bag 4 is detachably connected to the clamping end for clamping the sealed bag 4 and opening the bag opening 401, so that the sealed bag 4 can move with the lifting frame 2 and be put on the outside of the cryopreservation bag 7, so that when the cryopreservation bag is taken out, the sealed bag 4 is put on the outside of the cryopreservation bag simultaneously, and then the lifting frame 2 is grasped, the sealed bag 4 covers the cryopreservation bag, the lifting frame 2 hooks the protective frame 1, and the operation of moving and immersing in the water bath can be performed.
[0042] Understandably, the protective frame 1 has a certain counterweight, which can press down the cryopreservation bag to sink in the water; the insertion direction of the cryopreservation bag is such that its opening faces inward and is inserted into the open end 101, and after the sealing bag 4 is put on, it can be inserted with the bottom facing down.
[0043] In one embodiment, please refer to Figure 2 and Figure 3 To facilitate the sealing of the cryopreservation bag 7, the inner bottom wall of the protective frame 1 is provided with a protrusion 103 for suspending the tail end of the cryopreservation bag 7, so that it can be easily fitted onto the outside of the cryopreservation bag 7 when the sealing bag 4 is fitted. A stop block 104 is provided on the side of the protrusion 103 away from the opening 101 to prevent the cryopreservation bag 7 from falling out. When pulled out and immersed in water, it can prevent the cryopreservation bag 7 from falling out and floating up, respectively. A slope 105 is provided on the side of the protrusion 103 near the opening 101, and a curved surface 106 is provided between the stop block 104 and the protrusion 103. Both the slope 105 and the curved surface 106 are used to guide the bottom side of the opening 401 of the sealing bag 4 to slide, avoid the sealing bag 4 from getting stuck, guide the bottom side of the opening 401 of the sealing bag 4 to move along the length of the protective frame 1, and pass out from the side away from the opening 101.
[0044] In one embodiment, please refer to Figure 2 and Figure 4In order to slide on the protective frame 1 and form a hook, the lifting frame 2 includes an upper plate 21, a lower plate 22 and a limiting slider 23. The two ends of the limiting slider 23 are fixedly connected to the upper plate 21 and the lower plate 22 respectively. The limiting slider 23 is slidably connected to the inner side of the guide groove 102. The upper plate 21 abuts against the top of the protective frame 1 and the lower plate 22 abuts against the inner top wall of the protective frame 1, thereby forming a limiting guide, which can slide and hook along the guide groove 102; the groove opening of the guide groove 102 is connected to the opening 101.
[0045] In this embodiment, the slider 23 moves to the end of the guide groove 102, which is the end away from the opening 101. The limiting slider 23 abuts against the inner bottom wall of the guide groove 102 and forms a U-shaped hook structure with the upper plate 21 and the lower plate 22, which can lift and hook up the entire protective frame 1.
[0046] Furthermore, the upper plate 21 is provided with a handle 24 for easy lifting of the frame 2; the bottom of the protective frame 1 near the opening 101 is provided with a raised edge 107 for easy pulling out of the protective frame 1.
[0047] Furthermore, in order to quickly seal the opening of the sealing bag 4 after bagging, the inner side of the sealing bag 4 is provided with an interlocking seal strip, which can be aligned and pressed to form a preliminary seal.
[0048] Understandably, the interlocking seal is a self-sealing seal, a common sealing structure for existing sealed bags 4, consisting of two plastic strips that interlock to form a seal when pressed.
[0049] In one embodiment, please refer to Figure 2 and Figure 5 In order to provide clamping for the sealing bag 4, the clamping member 3 includes a rotating shaft 31 and a clamping plate 32. A torsion spring is provided between the clamping plate 32 and the rotating shaft 31. The torsion spring elastically pulls the clamping plate 32 to press it against the lifting frame 2. One side of the bag opening 401 of the sealing bag 4 is inserted between the clamping plate 32 and the lifting frame 2 to clamp the sealing bag 4. The bag opening 401 of the sealing bag 4 can be pulled open for the freezing bag to be set.
[0050] Understandably, the torsion spring is not shown in the figure. The torsion spring is an existing structural component, coaxially installed at the position of the rotating shaft 31, and the two ends of the torsion spring are respectively connected to the rotating shaft 31 and the clamping plate 32, providing elastic force in the torsional direction, which can elastically push the rotating shaft 31 and the clamping plate 32 to rotate, so that the clamping plate 32 is pressed onto the lower plate 22 of the lifting frame 2.
[0051] For further details, please refer to Figure 7In order to open the bag opening 401 of the sealing bag 4, the clamping plate 32 is provided with elastic rods 33. The elastic rods 33 are inserted into the inside of the bag opening 401 to provide support and open the bag opening 401. There are two elastic rods 33, located on both sides of the frozen bag. The elastic rods 33 are V-shaped and elastically folded. The elastic range of the elastic rods 33 is mainly to meet the rotation of the sealing clamp assembly 5. That is, the elastic rods 33 can be elastically folded when the sealing clamp rod 53 rotates, so that the sealing clamp rod 53 can move from the upper plate 21 to the lower plate 22, and rotate in the opposite direction to pass over it.
[0052] Furthermore, the protective frame 1 is provided with several openings to allow air circulation and water circulation for immersion in a water bath.
[0053] Furthermore, to enhance sealing performance, a sealing clamp assembly 5 is also included. The sealing clamp assembly 5 includes a central shaft 51, a spring telescopic rod 52, and a sealing clamp rod 53. The central shaft 51 is rotatably connected to the upper plate 21. The two ends of the spring telescopic rod 52 are respectively connected to the central shaft 51 and the sealing clamp rod 53, and are used to elastically pull the sealing clamp rod 53 toward the central shaft 51, so that the sealing clamp rod 53 is in a position state that presses against the surface of the lower plate 22 to seal the sealing bag 4.
[0054] The spring telescopic rod 52 includes a fixed cylinder, a spring, and a telescopic rod. The spring is built into the inside of the fixed cylinder, and both ends of the spring are connected to the inner wall of the fixed cylinder and the telescopic rod, respectively. The telescopic rod is slidably connected to the fixed cylinder. When the elastic rod is pulled, it retracts into the inside of the fixed cylinder. When the sealing clamp rod 53 is pulled to the position of the lower plate 22, the spring is stretched, providing a pulling force to drive the telescopic rod to move, thereby pressing the sealing clamp rod 53 onto the lower plate 22, which can form a press-fit reinforced seal on the sealing bag 4.
[0055] This utility model also provides a cryopreservation rack, including a protective frame 1 as described in any of the above claims; it also includes a rack body 6, which includes a base frame 61 and compartment drawers 62. The compartment drawers 62 are slidably connected to the base frame 61, and the side of the compartment drawers 62 is provided with a plurality of insertion slots 621. The protective frame 1 is inserted into the inner side of the corresponding insertion slot 621. The direction of the insertion slots 621 is perpendicular to the axial direction of the base frame 61, i.e., perpendicular to the pulling direction. This allows the protective frame 1 to be pulled out from the side. In use, multiple rack bodies 6 can be arranged in an array, and one compartment drawer 62 can be pulled out at a time, allowing the corresponding protective frame 1 to be pulled out from the side.
[0056] To better understand this utility model, the following is combined with... Figures 1 to 8The technical solution of this utility model is described in detail as follows: Pull out the compartment drawer 62, align the lifting frame 2 containing the sealed bag 4 with the corresponding insertion slot 621, and then pull out the protective frame 1 through the protruding edge 107. The lifting frame 2 is inserted into the guide groove 102. During the pulling action, the sealed bag 4 is placed on the cryopreservation bag 7, and the bag opening passes through the protective frame 1. The protective frame 1 is pulled out from the insertion slot 621, and the sealed bag 4 is placed on the outside of the cryopreservation bag 7. Then, the air is squeezed out of the sealed bag 4 through the perforation, and the interlocking seal is pressed and sealed. Then, the sealing clamp assembly 5 is operated. The sealing clamp rod 53 is rotated to the lower plate 22, and wrapped around to the outside of the sealed bag 4 for pressing and forming a secondary seal. By directly holding the lifting frame 2, the protective frame 1, the sealed bag 4, and the inner cryopreservation bag 7 can be moved and immersed in the water bath. In the water bath, the protective frame 1 is in a vertical position, see reference. Figure 8 The cryopreservation bag 7 can be limited and prevented from floating. The lifting frame 2 can be shaken by hand to shake the cryopreservation bag together for water bath thawing.
[0057] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
